14.19
Cycle time variance calculation
Cycle time of the variance calculation in ms.
14.20
Status variance calculation
Internal status of the variance calculation.
14.21
Position monitoring error threshold
Error threshold for position actual value monitoring, see
bit 7. Mechanical angle
in degrees.
An electrical angle less than 45° is recommended using synchronous machines. Thus a
positive feedback in the current closed loop can be avoided at a slowly growing position
actual value error. Recommendation for setting:
14.22
Position monitoring error
Present difference between the digital position and the analog position from the sine-co-
sine traces. Updating interval approx. 500 ms. Mechanical angle in degrees.
The digital resolution
and the number of pulses
resolution of the encoder.
5
Monitoring of the position initialization active
6
Variance monitoring active
7
Monitoring of the position actual value.
This monitoring must not be enabled at length measuring devices (linear
encoders).
Bit no.
